Heidi Klum reveals the workouts she does to stay fit as a mother of 4 kids

• Heidi Klum says she stays fit by playing with her kids.• She credits bike rides, hiking, and jumping on the trampoline for staying fit.• She also eats healthy so she can live a better life.

Heidi Klum has been one of the most beloved supermodels in the world for over a decade (and she also has killer Halloween costumes). But obviously as a mother of four, finding time for herself to exercise and eat well can be a challenge.

"I don't have time for workouts every day," Klum told the magazine. "Being the mother of four kids is a workout in itself! Balancing my work and their schedules makes it hard to find time for a traditional exercise routine, so we try to do as many outdoor activities as a family as possible."

As for what those activities are, Klum said: "We love to go on bike rides, take our dogs hiking, or jump on the trampoline."

"That's the best way to stay fit and healthy," she added. "Do things that don't feel like work."

"The myth that models don't eat is totally not true," she told Shape. "I just think that because we're in this business, we have to choose more wisely. It's not just about doing the cardio so that you're nice and fit, and slim and trim, but your heart needs to pump, too, and that is very important."

And though staying motivated, active, and eating right can be a challenge, she says that she thinks "big picture" and reminds herself that it's all in an effort to "live a better and healthier life."

"I love my shape because it's mine," she said. "At the end of the day, it's not what anyone else thinks about my body but how I feel about myself. I'm working it and owning it!"
